Topic: Neuroscience



Expert: Kai Schreiber
Date: 2/12/2007
Subject: ciliary body

Question
dear
as we know when ciliary bodies contract the ligaments will get looser and lens tend to rise its globe shape so we can see things that are not far from our eye, either as we know ciliary bodies are radial muscles, how contraction of these radial muscles will diminish the distance between the ciliary bodies and lens that makes the ligamants looser?
please help me with this
thanx alot

Answer
Hello Mohammad,

the ciliary muscle actually is a ring surrounding the eye, so when it constricts, it releases the tension of the ligaments and allows the lens to bulge. Conversely, when the ciliary muscle relaxes, the ligaments pull on the lens, flattening it.

You can see the anatomy there:

Best,
Kai
